LOOM FOR WEAVING DOUBLE PILED FABRICS.

SPECIFICATION forming part of'Letters Patent No. 374,064, dated November 29, l 887.

7 Application filed September 15, 1885. Serial No. 177,132. (No model.)

To aZZ whom it may concern.-

Be it known that 1, Russian. HANDY, of Manville, in the county of Providence and State of Rhode Island, have invented certain new and useful'lmprovements in Looms for Weaving Double Piled Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming apart of this specification. I

This invention has reference to the class of looms in which is woven double piled fabricthat is to say, a fabric consisting of two backs of interwoven fabric with pile-threads extending from one fabric to the other, which pilethreads are afterward cut-,so as to form two separate sheets of velvet, velveteen, or other piled fabric.

The invention consists in the peculiar and novel construction of the mechanism by which the delivery of the pile warp to the harnesses is regulated and the pile take-up device is controlled,and of the novel constructions of parts, as will be more fully set forth hereinafter.

Piled fabric is usually woven with a backfrom which a large number of pile-threads project to form a-velvety surface, such as is the case in silk, cotton, and other velvet, and in velvet carpets. The velvet surface is formedby weaving a large number of loops into the back or fabric and then cutting these loops to form the soft velvet surface. Recently two sheets of this fabric have been woven simultaneously in a special loom, the pile extending from one back or fabric to the other, so that when the woven fabric has been splitinto two sheets by cutting the pile with a knife two sheets of velvet are'produced.

The present invention refers to looms for weaving the double pile fabric.

Figure 1 is a side view of part of a loom, showing the mechanism for delivering and the device for taking up the pile warp and the mechanism co-operating therewith. Fig. 2is an enlarged view of the pile-warp rod and the Fig. 3 is a view, partly in section," of the star and hand wheel by which the let-off mechanism controlling the delivery of the pile warp is operated. Fig. 4. is a sectional viewof the hand-wheel, shown in'connection with the star-wheel,taken on line 44, Fig. 3.

'mounted in a pair of swinging arms, a, hinged to the loom-frame, and only one of which is shown, the fellow arm being in line therewith on the other side of the frame. This roller is a heavy metal roller and maintains the tension on the pile warp, which passes about roller a, as shown, and thence around the roller a and over the roller a whereby thedelivery of the pile warp is limited to the rotation of the rolls a and a", in a manner well known in this construction of warp-delivery rollers. The rolls a and a are eachprovided at theremote end with afixed' gear-wheel, J. These gears intermesh and cause the connected rolls torotate oppositely at the same speed in lettingoff the yarn. The pile warp passes from the roller a down under the pile-warp rod G, and thence to the heddle or harness by which the pile warp is sprung to enter the upper and lower fabric and is interwoven with the'same by the filling-threads. The warp from the beams B and G is delivered to the harnesses in the usual manner.

H is ahand-wheel provided on its inner face with the boss h. This hand-wheel 1-1 is secured to'the crankshaft I by a spline, s, so that while itmust rotate with the crankshaft it can be drawn out longitudinally upon the shaft against the pressure of the sp'iral'spring z. The boss h has a cavity or notch, 15, formed on one side, in the center of whichapin, h, is placed. This pin enters one of the slots in the star-wheel 70, which is secured to the shaft K, at each revolution of the shaft I and hand-wheel H.

. The star-wheel 7c is provided with five slots and five concaved faces between the slots, which faces form segments of a circle equal to the diameter of the boss 72, so that during the revolution of the boss h the star-wheel is firmly locked by the contact of one of the five faces against the circumference of the boss it until the cavityt reaches the star-wheel, when the pin h in the center of the cavity, which pin projects slightly beyond the periphery of the boss, enters one of the slots of the starwheel k and turns the same one-fifth of a revolution, the points on the star-wheel entering the cavity. As soon as this partial rotation of the star-wheel is accomplished, the same is again firmly held against rotation by one of the faces bearing against the periphery of the boss It. By drawing thehand-wheel H outward against the spring z'the star-wheel can be disengaged from the pin h on the boss 71, so as to permit the movement of the warp-delivery mechanism, which is necessary in adjusting the tension on the pile warp. v

To the shaft K, to which the star-wheel 7a is secured, is also secured a bevel-gear, c, which gears into and communicates its motion to the bevel-gear k on the vertical shaft L, the upper end of which shaft L is provided with a worm, w, gearing into and rotating the wormgcar Z, secured to the shaft of the roller a.

It will be apparent that for each revolution of the shaft I by means of the star-wheel the bevel-gears, the shafts K L, and the worm-gear Zthe rollers a a will be rotated a fixed distance, and that the length of pile warp delivered will be equal to the motion of the periphcries of the rollers a a and also that the rollers a a will be firmly held against rotation as long as one of the faces of the star-wheel It: bears against the periphery of the boss h.

To facilitate the turning of the shaft L when the hand-wheel H is drawn out and the tension of the pile warp is-to be regulated, the hand-wheel l is secured to the shaft L, as shown in Fig. 1.

On the vertical shaft L, below the handwheel Z, is secured the beveled gear 9, gearing into the beveled gear 9, placed on a looselymounted horizontal shaft, 0*, on which the starcam g is secured. The proportions of the gears between the star-wheel 7c and the star-cam g are such that both will make one-fifth of a revolution and simultaneously. The star-cam g has five concavities, in each of which the roller 9 journaled on the trip-lever 9, can

firmly rest during the time the star-wheel 7c is locked against rotation. At each partial rotation of the star-cam the roller gfland with it the lever g, is raised. The lever 51* is provided on its outer end with a hook, 9 or equivalent means for securing the tension-spring g, which is also secured to the tilt-lever on the opposite end of which the pile-rod G is secured, as is shown in Fig. 2 on an enlarged scale. Two sets of the devices shown in Fig. 2 are used on one 1oomone set located near each end of the loom-and the pile-rod G extends over the whole width of the pile warp.

The pile-warp rod G, together with the immediately-connected parts for vibrating the rod, I term the pile-take-up device, since by the action of said parts the slack pile-thread is taken up as delivered by the pile-let-off apparatus above described.

The operations of these devices in connection with the operation of the loom are as follows: The shaftI makes one revolution to each reciprocation of the shuttles and turns the star-wheel onefifth of a revolution, which motion is communicated to the roller a and roller a, whereby the pile warp is delivered to the pile-rod G, which at the sameinstant is depressed, and,bearing on the pile warp, takes up the slack therein and delivers the same to theharness to form the interwoven pile-threads, which constitute the pile of the fabric.

The mechanism for operating the lay, the shuttles, and the harnesses are not shown. They are of the old and well-known form, and form no part of this invention.
